Could you tell me in more detail about another strings you want to change?
Actually, Thank you for your feedback we added a Color, Opacity, Width, Straight.
(This change will be reflected at new version which will be released on Friday.)
Is there anything we added more?

We’d like to translate the strings inside of “Table of Contents” popover? We cannot find them inside the Localizable.strings file. Are there somewhere else or are not available?
We should have them all so the translated app could have the same language everywhere.
